error in namespace generation with maven plugin

[altair2010]

this command line
java -jar "tlbimp-2.1.jar" -o "target\generated-sources\com4j\java" -p "my.test" "C:\Program Files (x86)\Microsoft Office\Office14\MSWORD.OLB"

generate java files in folder target\generated-sources\com4j\java\my\test\events using a right package definition package my.test.events;

but the maven plugin

        <plugin>
            <groupId>org.jvnet.com4j</groupId>
            <artifactId>maven-com4j-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>
                    <id>Word 2010 (OFFICE14/MSWORD.OLB)</id>
                    <goals>
                        <goal>gen</goal>
                    </goals>
                    <configuration>
                        <!--<libId>00020905-0000-0000-C000-000000000046</libId>-->
                        <file>C:\Program Files (x86)\Microsoft Office\Office14\MSWORD.OLB</file>
                        <package>my.test</package>
                    </configuration>
                </execution>
            </executions>
        </plugin>

generate some files in folder target\generated-sources\com4j\java\events with an invalid package package .events; like for _CommandBarButtonEvents class
